This invention relates to resilient supports and more particularly to asupport or suspension means designed for use I in connection withmechanical refrigtrating apparatus for supporting the power uhit thereofwhereby the vibrations emanating from the moving parts thereof may beabsorbed and transmission of the same to the refrigerator or otherassociated. structure prevented.

Tn mechanical refrigeration it is customary to provide a power unit suchfor instance as an electric motor together with a compressor or pump anda rotor such as a fan and to as sociate this mechanism with arefrigerator 115 box or the like. The vibrations set up by the movementof the parts inoperation are, in the case of a direct or rigid mountingof these parts, transmitted directly to and throughout the refrigeratorbox and prove noisy and othl erwise objectionable. Many means have beenattempted for dissipating or otherwise absorbing thesevibrations so asto prevent their transmission to the refrigerator box, but theseheretofore known devices have so far proven to be-either complicated,relatively crude, in-

. efficient or otherwise unsatisfactory.

Tt is therefore the primary object of this invention to provide aresilient support or mounting for the operating mechanism of a tomechanical refrigerator and vide a support of this character which isdis tinguished by its simplicity, efficiency and cheapnessin manufactureand installation. Various other objects, advantages and 35 novel detailsof construction of the invention will be made more apparent as thisdescription proceeds especially whenconsidered' in connection with theaccompanying drawings, wherein to m Figure. 1 is a fragmentaryelevational view of a refrigerator box showing the operating mechanismfor producing mechanical refrigeration and showing the application of myinvention. I v Figure 2 is a plan view of a base or support forming apart of the herein described invpntion.

showing a modified form of construction.

Referring now more particularl to the drawings wherein like reference 0aracters further to proenlarged fragmentary sec- 1 indicate like partsit will be noted that in Figure 1 l have shown fragmentarily arefrigerator box 10 adapted to be electrically refrigerated, the lowerportion of the box being provided with a compartment 11 provided with abottom 12. It is Within the com- 1 part-me-nt 11 that I propose mountingthe mechanism for producingmechanical refrig oration and in which thesupport constituting this invent-ion is disposed. l have shown inconventional form only a power unit such as an electric motor 13 havinga driving connection with a compressor or pump. 14 together with a fan15 and a condenser 16. In practice these parts are mounted upon a base17.

ln carrying out this invention l preferably 7 employ a supplemental base18 formed preferably, although not necessarily, of wood,

bolted or otherwise secured at a plurality of points as indicated at 19to the'bottom 1 2 of the refrigerator box. This supplemental base isformed with a plurality, here shown as three, suitably spaced pockets orrecesses 20.

The base 17 which directly supports the refrigerating mechanism isprovided with a corresponding number of threaded apertures W 21, inwhich are inserted threaded pins or studs 22. The lengthof these pins 22is so selected as to be less than and to be housed within the customaryperipheral flange 23 on the base 17. Each stud 22 has fixed thereto acoil spring 24 which is adapted to surround the associated stud 22 andto project beyond the end thereof and into the-associated pocket 20 ofthe supplemental base 18. The length and strength of the springs M issoselected to that they will support the base 17 spaced from thesupplemental base 18 as suggested in Figure 3. lllith' such anarrangement vibrations or other shocks emanating from the moving asparts supported upon the base 17 are dissipated and absorbed bycthesprings 24: to prevent their transmission to the supplemental base18-and consequently to the refrigerator, box. 7 too In Figure 4 T haveshown the base 17 as provided with feet or legs 25 secured to the underside thereof. The lower end of each leg 25 is provided with a threadedaperture 26 adapted to be engaged by the threaded portion of a threadedpin or stud 27 to which a spring 28 is attached. With such aconstruction the base 17 may be supported directly upon the floor orupon a suitable portion of the refrigerator box and the vibrations setup by the moving parts supported upon the base 17 will likewise beabsorbed or dissipated by the springs 28. Y

It will be readily apparent that While I have illustrated an embodimentof the invention in which a supplemental base 18 is utilized, that thissupplemental base may be eliminated and the base 17 supported directlyby the springs 24 upon the floor 12 of the refrigerator box which latterpart may or may not be formed with the recesses or pockets 20. However,with the embodiment of the invention shown in Figures 1 to thesupplemental base may have the recesses 20 properly located therein atthe factory and either bolted to the refrigerator box at the factory orsent separately to the distributor or user with instructions forattachment to the refrigerator box in which the electrical refrigeratingapparatus is to be installed. In such an instance the properly spacedpockets not only insurev a correct positioning of the base and the partscarried thereby, once the supplemental base has been correctly placed,but also prevents any accidental laterally shifting of the base 17 inuse.

The threaded studs 22 may be quickly and easily removed or replacedshould they become worn or broken or additional points of support may beprovided merely by forming ad itional threaded apertures in the base 17and inserting the threaded studs provided with the springs 2 1 in thethreaded apertures.

The invention therefore is distinguished by its simplicity, efliciencyand adaptability in practice thereby making the same commerciallysatisfactory and acceptable.

WVhile the invention has-been described herein somewhat in detail itwill be readily apparent to those skilled in this art that variouschanges and modifications may be resorted to without departing from thespirit and scope of this invention and to this end reservation is madeto make such changes as may come within the purview of the accompanyingclaim.

\Vhat I claim as my invention is:

A support having a base, a supplemental base detachably secured to saidbase having a plurality of spaced recesses therein, a third baseconstituting a support for mechanical refrigerating apparatus positionedsubstantially above the supplemental base and having a depending flange,members threadedly engaging said third base and extending downwardlytherefrom terminating short of said supplemental base and concealed bysaid depending flange, and yieldable elements surrounding the membersand engagin said recesses for yieldably supporting the third basespaeedfrom the supplemental base.

In testimony whereof I aiIix my signature.
